Why is my Fujitsu ASU12C1 not cooling well?

  Kristin GarciaAug 6, 2025
  Several factors can impact the cooling performance of your Fujitsu Air Conditioner. Ensure the air filter is clean and that the intake grille or outlet port aren't blocked. Check if the room temperature settings (thermostat) are correctly adjusted. Also, make sure no windows or doors are open, and bright sunlight isn't entering the room. Other factors include the presence of heating apparatus, computers, or too many people in the room. Finally, check if the unit is set to SUPER QUIET operation.

Why Fujitsu Air Conditioner doesn’t operate immediately?
- B
  Brandon TaylorAug 11, 2025
  If your Fujitsu unit is stopped and then immediately started again, the compressor will not operate for about 3 minutes to prevent fuse blowouts. Also, whenever the Power is disconnected and then reconnected to a power outlet, the protection circuit will operate for about 3 minutes, preventing unit operation during that period.

  If your Fujitsu Air Conditioner isn't operating, check for a power failure first. Then, verify if a fuse has blown or a circuit breaker has tripped. Ensure the POWER switch is not in the OFF position and that the timer isn't operating.

Why is my Fujitsu ASU12C1 Air Conditioner making noise?
- S
  Sharon MeltonAug 27, 2025
  During operation, and immediately after stopping your Fujitsu Air Conditioner, you might hear the sound of water flowing in the piping. Also, noise may be particularly noticeable for about 2 to 3 minutes after starting operation due to the sound of coolant flowing. A slight squeaking sound may also occur due to minute expansion and contraction of the front cover because of temperature changes.

Why does Fujitsu ASU12C1 emit mist or steam?
- R
  Ryan JohnstonAug 31, 2025
  During Cooling or Dry operation, a thin mist may be seen emitted from the indoor unit of your Fujitsu Air Conditioner. This results from the sudden cooling of room air by the air emitted from the air conditioner, causing condensation and misting.
